Thanks for the kind review; I'm glad you've enjoyed the game. ^-^
You aren't the only person to complain about the snowballing element of the calculations, and in fact I agree with you! The upcoming update (version 0.81.x) includes a few tweaks to make this element less punishing. It doesn't entirely remove the positive feedback loop of investment returns, but it does offer some options so that early mistakes don't leave players unable to engage with this element.
